Description

Technical Field

[0001] This utility model relates to the field of dental elevator technology, specifically a dental elevator with protective function. Background Technology

[0002] A dental elevator is a tool used to loosen a tooth before extraction, making it easier to remove the tooth. A dental elevator consists of three parts: a blade, a handle, and a shaft. Based on the principles of applied mechanics and practical needs, there are various types of dental elevators, including straight elevators, curved elevators, apical elevators, Bass elevators, and triangular elevators. The principle of a dental elevator loosening the tooth root is mainly based on three forces: lever, wheel and axle, and wedge. The straight elevator is the most commonly used in clinical practice.

[0003] The working principle of dental elevators is based on the lever principle. Through the combination of the blade, lever, and handle, the applied force is transmitted to the tooth root. In actual operation, medical staff will use their fingers to support the dental elevator, thus providing a fulcrum for the lever movement of the dental elevator. However, when using dental elevators, the use of fingers to support the dental elevator can easily cause the dental elevator to slip when force is applied due to the small contact area and the low coefficient of friction between the fingers and the dental elevator. This can easily cause damage to the patient's adjacent teeth or bone plate, thereby reducing the safety of dental elevators during use.

[0004] Therefore, there is an urgent need for a dental elevator with protective functions to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dental elevator with protective function, comprising a handle and a dental bar disposed at one end of the handle, wherein a dental blade is fixedly connected to the end of the dental bar away from the handle, and further comprising a support component disposed on the dental bar for providing fulcrum support when the dental blade is used;

[0006] The support assembly includes a rotating ring rotatably connected to the tooth bar near the handle side wall. A first rotating plate is hinged to the side wall of the rotating ring. A protective ring is sleeved on the side wall of the tooth bar. A second rotating plate is hinged to the side wall of the protective ring. A support plate is provided at the opposite end of the first and second rotating plates. The first and second rotating plates are connected to the support plate through a connecting assembly.

[0007] The support plate has an arc-shaped groove on the side away from the tooth bar, and the inner wall of the arc-shaped groove is frosted.

[0008] The connecting assembly includes two sets of symmetrically arranged connecting plates fixedly connected to the support plate near the tooth bar. A connecting rod is rotatably connected between the two connecting plates. The ends of the first rotating plate and the second rotating plate that are close to each other are respectively connected to the two connecting rods. A limiting component for limiting the first rotating plate is provided on one of the four connecting plates near the first rotating plate.

[0009] The limiting component includes a push plate slidably connected to one side of the connecting plate. A limiting rod is fixedly connected to the side of the push plate near the connecting plate. A spline plate is fixedly connected to the end of the limiting rod away from the connecting plate. A spline hole is opened on the side of the connecting rod near the spline plate. The spline hole is matched with the spline plate. The connecting plate is provided with a telescopic component for extending and retracting the spline plate. In the initial state, the spline plate is inserted into the spline hole under the elastic action of the telescopic component.

[0010] The bottom wall of the spline hole is provided with a clearance hole, the inner diameter of which is larger than the outer diameter of the spline plate.

[0011] The telescopic assembly includes two symmetrically arranged T-shaped rods fixedly connected to the side of the connecting plate near the push plate. The two T-shaped rods are slidably connected to a telescopic plate. One end of the two telescopic plates is connected to the push plate. Springs are sleeved on the side walls of the two T-shaped rods. The two ends of the two springs are respectively connected to the telescopic plate and the connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model's protective dental elevator, through the setting of the support component, and with the cooperation of the connecting component and the limiting component, provides support and protection for the dental elevator during leverage movement, thereby reducing the risk of slippage due to force during use, and consequently reducing the probability of damage to adjacent teeth or bone plates of the patient, thus improving the safety of the dental elevator during use. After the dental elevator is used, it protects the tooth edge, thereby reducing the risk of collision damage caused by the exposed tooth edge or accidental cuts to medical staff.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figures 1-7 The illustrated toothed elevator with protective function includes a handle 101 and a toothed bar 102 disposed at one end of the handle 101. A toothed blade 103 is fixedly connected to the end of the toothed bar 102 away from the handle 101. The elevator also includes a support component disposed on the toothed bar 102 for providing fulcrum support for the toothed blade 103 when in use.

[0025] The support assembly includes a rotating ring 201 rotatably connected to the side wall of the toothed bar 102 near the handle 101. A first rotating plate 203 is hinged to the side wall of the rotating ring 201. A protective ring 202 is sleeved on the side wall of the toothed bar 102. A second rotating plate 204 is hinged to the side wall of the protective ring 202. A support plate 205 is provided at the opposite end of the first rotating plate 203 and the second rotating plate 204. The first rotating plate 203 and the second rotating plate 204 are connected to the support plate 205 through a connecting assembly.

[0026] It should be noted that, through the design of the support components, in conjunction with the connecting and limiting components, the elevator provides support and protection during lever movements, thereby reducing the risk of slippage due to force during use. This reduces the likelihood of damage to adjacent teeth or bone plates, thus improving the safety of the elevator during use. After use, the elevator also protects the tooth edge 103, reducing the risk of collision damage or accidental cuts to medical personnel caused by the exposed tooth edge 103.

[0027] Please see Figure 4 The support plate 205 in the figure has an arc-shaped groove 206 on the side away from the tooth bar 102, and the inner wall of the arc-shaped groove 206 is frosted.

[0028] It should be noted that the arc-shaped groove 206 and the frosted inner wall treatment increase the contact area and friction with the support plate 205.

[0029] It is worth noting that the sidewalls of the support plate 205 are also frosted.

[0030] Please see Figure 4 The connecting assembly shown in the figure includes two sets of symmetrically arranged connecting plates 301 fixedly connected to the support plate 205 near the toothed bar 102. A connecting rod 302 is rotatably connected between the two connecting plates 301. The ends of the first rotating plate 203 and the second rotating plate 204 that are close to each other are respectively connected to the two connecting rods 302. A limiting assembly for limiting the first rotating plate 203 is provided on one of the four connecting plates 301 near the first rotating plate 203.

[0031] It should be noted here that the connection components are configured to enable the first rotating plate 203 and the second rotating plate 204 to be rotatably connected to the support plate 205.

[0032] Please see Figures 4-6 The limiting component shown in the figure includes a push plate 401 slidably connected to one side of the connecting plate 301. A limiting rod 402 is fixedly connected to the side of the push plate 401 near the connecting plate 301. A spline plate 403 is fixedly connected to the end of the limiting rod 402 away from the connecting plate 301. A spline hole 404 is opened on the side of the connecting rod 302 near the spline plate 403. The spline hole 404 is matched with the spline plate 403. The connecting plate 301 is provided with a telescopic component for telescopically extending and retracting the spline plate 403. In the initial state, the spline plate 403 is inserted into the spline hole 404 under the elastic action of the telescopic component.

[0033] It should be noted here that the limiting component is used to limit the first rotating plate 203, thereby limiting the protective ring 202 after it has moved to a new position.

[0034] Please see Figure 5 The bottom wall of the spline hole 404 in the figure is provided with a clearance hole 405, and the inner diameter of the clearance hole 405 is larger than the outer diameter of the spline plate 403.

[0035] It should be noted here that the clearance hole 405 provides space for the spline plate 403 to move.

[0036] Working principle: When using the dental elevator to operate on the patient's teeth, the medical staff first take the dental elevator out of the storage box, then hold the handle 101 with one hand and hold the support plate 205 with the other hand. While holding the support plate 205, the push plate 401 is pushed. Under the guidance of the pushing force and the telescopic component, the spline plate 403 at one end of the limiting rod 402 is pushed out of the spline hole 404, thereby releasing the limitation between the first rotating plate 203 and the connecting plate 301.

[0037] After the limiting positions of the first rotating plate 203 and the connecting plate 301 are released, the support plate 205 can be pulled away from the toothed bar 102. This will cause the first rotating plate 203 and the second rotating plate 204 to rotate, thereby causing the protective ring 202 to move along the side wall of the toothed bar 102 closer to the handle 101. When the protective ring 202 moves to an appropriate position on the side wall of the toothed bar 102 (refer to...), Figure 7 Stop pulling the support plate 205 and release the push plate 401. At this time, under the elastic action of the telescopic component, the spline plate 403 will be driven to insert into the spline hole 404, thereby forming a limit on the connecting rod 302, which in turn limits the first rotating plate 203, and then realizes the limit on the protective ring 202 after the movement position.

[0038] After adjusting the position of the protective ring 202, the cutting edge 103 at one end of the dental elevator 102 can be moved to the side of the tooth to be loosened. Then, the medical staff holds the handle 101 with one hand, bends the index finger of the other hand and abuts its surface against the inner wall of the arc groove 206 of the support plate 205. At the same time, the thumb and middle finger pinch the two sides of the support plate 205 tightly. When loosening the patient's tooth, force can be applied to the handle 101 and the force can be transmitted to the tooth with the support plate 205 as the fulcrum, thereby achieving the loosening of the tooth. In the process of force transmission with the support plate 205 as the fulcrum, the contact area and friction with the support plate 205 are increased because the three fingers of the medical staff are pressed against the support plate 205. This improves the support and protection of the dental elevator when it is in lever movement, thereby reducing the risk of the dental elevator slipping due to force during use and reducing the probability of damage to the patient's adjacent teeth or bone plate, thus improving the safety of the dental elevator during use.

[0039] After the dental elevator has been used and cleaned and disinfected, the protective ring 202 is fitted around the periphery of the dental blade 103 by pushing the support plate 205 closer to the dental bar 102 and by the limiting action of the limiting component, thereby protecting the dental blade 103 (see reference). Figure 1 This reduces the risk of impact damage or accidental cuts to healthcare workers caused by the exposed tooth blade 103.

[0040] Example 2

[0041] Please see Figure 5 This embodiment further illustrates Example 1. The telescopic assembly shown in the figure includes two symmetrically arranged T-shaped rods 502 fixedly connected to the side of the connecting plate 301 near the push plate 401. The two T-shaped rods 502 are slidably connected to the telescopic plate 501. One end of the two telescopic plates 501 is connected to the push plate 401. Springs 503 are sleeved on the side walls of the two T-shaped rods 502. The two ends of the two springs 503 are respectively connected to the telescopic plate 501 and the connecting plate 301.

[0042] It should be noted here that the telescopic component is designed to provide guidance and elastic reset for the movement of the push plate 401.
